Key Advantages of Our Phosphite Antioxidant

Exceptional Thermal Stability

Engineered to withstand high processing temperatures, this antioxidant safeguards polymer integrity, making it an ideal choice for demanding applications where melt flow and color stability are critical.

Unsurpassed Hydrolytic Stability

Unlike many other phosphites, our product maintains its effectiveness and free-flowing powder form even under extremely humid conditions, providing reliable performance and extended shelf life.

High Efficiency and Versatility

Used at low dosages, this antioxidant offers significant benefits in polypropylene systems and provides excellent color and melt flow stability in both HDPE and LDPE. Its low volatility makes it suitable for high-temperature engineering plastics, solidifying its position as a versatile polymer stabilizer.

Broad Application Spectrum

Polypropylene (PP) Stabilization

Our phosphite antioxidant delivers high efficiency and excellent color and melt flow stability in PP systems, crucial for manufacturers seeking high-performance materials.

Polyethylene (PE) Enhancement

In both HDPE and LDPE, this antioxidant ensures excellent color and melt flow stability, making it a preferred additive for plastic manufacturers.

Engineering Plastics Performance

Its low volatility and ability to withstand high processing temperatures make it an excellent choice for engineering plastics like Polycarbonate (PC), protecting against degradation.

Color and Melt Flow Control

Essential for applications requiring precise color retention and stable melt flow, this antioxidant is a key component for achieving superior product quality in various polymer processing sectors.
